"My sleeping quality was improved further more."
Purchase reason: I am an audiophile and very keen to improve sound quality from every perspective. Recently I bumped into some article said Schumann resonance can help on sound quality so I bought some Schumann wave generator, at the mean while, I also google around to search the introduction of it, so I started to understand that Schumann resonance can be generated along with negative ion, especially in a thunderstorm, so I carry on googling, your website just pop up when I trying :negative ion generator.
About effects: I have used Schumann resonance generator to improve my sound quality, as well as my sleeping quality before I bought medical ion mini, but after I use both in my bedroom, my sleeping quality was improved further more, I felt less groggy when I wake up in the morning, I feel more energy during the day, I also recover from fatigue quicker (I work out in gym 4-5 times every week)
Other comments: The stock switch power supply looks cheap, from audiophile point of view, a better linear power supply always render better result, in terms of sound quality, stability, etc. So I recommend to try a linear power supply instead of switch one, it suppose to be better.
